SOUTHBRIDGE, MASSACHUSETTS, ASSIGNOR TO AMERI- OF SOUTHBRIDGE, MASSACHUSETTS, A VOLUNTARY PROCESS OF FORMING TEMPLE END PIECES.

Application filed January 2, 1918.

To aZZ whom '52 may concern.

Be it known that I, lYILLIAtii' H. BOU- TI'JLLI'J, a citizen of the United States, residing at Southbridge, in the county of Voicester and State of Massachusetts, have invented certain new and useful Improvements in Processes of Forming Temple End Pieces, of which the following is a specification.

This invention relates to new and useful improvements in processes for forming temple end pieces and has for its main object to form a temple end piece having an offset portion formed therein to provide a bearing for the head of the temple side thus eliminating the necessity of sawing the end pieces after they have been applied to the ends of the lenses.

Another object of the present invention is to provide a process of forming temple end pieces wherein the offset is formed during the stamping operation and the material stamped or shaped is cut from the blank and trimmed of all rough edges atone operation thus eliminating the necessity of sawing the recesses in the end pieces and polishing them to provide a smooth bearing for the temple head.

With the above and other objects in view the invention consists in the novel features of construction and the combination and arrangement of parts hereinafter more fully forth, pointed out in the claims and shown in the accompanying drawings in which Figure I is a plan of a gold filled blank from which the end piece is stamped.

Fig. II is a plan view of the blank after being stamped.

Fig. III is a side elevation of the blank after being stamped.

Fig. IV is a side elevation of the end piece after being punched from the blank.

Fig. V is a plan view of the finished article.

Fig. VI is a section showing the punching operation.

Fig. VII is a plan view showing the operation of cutting the end piece from the blank eliminating the punching and trimming operation.

of theend piece in its and Fig. IX is a longitudinal sectional view of two end pieces arranged in their respective positions.

Fig. X represents a fragmentary perspective view illustrating a frame embodying my improved end piece.

In carrying out my process I first have a plurality of blanks cut to the preferred size as illustrated in Fig. I. The blank which is herein indicated by the numeral 1 is then put in a die and stamped out to form the bulged portion indicated at 2 in Fig. II, said portion having an offset as at 3 which provides for the temple head bearing when the end pieces are secured to the lenses. After the bulged portion 2 has been formed the blank is put in a die and a punch 4 used to punch the end piece 5 from the blank 1 which leaves the end piece with a rough bur at its edges as indicated at 6 which is cut or trimmed off by placing these end pieces in another die and having a knife passing thereover and trimming these burs off which will leave the finished cnd piece as shown in Fig. V.

It will be readily noted from the above that by forming the offset portion 3 at the same time the end piece is stamped it will eliminate the necessity of sawing the temple bearing recess in the ends of these end. pieces after they have been applied to the lenses and also eliminate the necessity of putting a smooth finish on the roughened faces of the recess caused by the sawing operation. Thus there will be not only a considerable saving in the labor used in the making and mounting of these end pieces but also a saving in the use of the machinery used to produce these goods.

In another form of the process the blank 1 is stamped out to provide the bulge portion' 2 and after this has been done the bulge portion is placed in a die and severed from the blank 1 by means of a knife as illustrated in Fig. VII. Thus the operation of punching the end piece from the blank and of cutting the burs is carried out in one operation saving considerable time and labor as will be readily apparent. Now while I have described this process as especially used finished condition,

cause the precious metal to be in connection with gold filled stock it will be readily apparent that the same may be used equally as well with any kind of stock. It will also be noted that by forming the offset 3 in the blank when stamped as described and illustrated it will eliminate the necessity of sawing the temple butt recess in the ends of the end pieces and the polishing of the walls of this recess after the sawing operation has been completed.

While I have shown in the accompanying drawings certain types of tools especially for use in the forming of my improved end piece it will be apparent that the process may be readily carried out by the use of a set of tools similar to those shown in the accompanying drawings or any other tools which will do the work equally as well.

Fig. VIII is, as previously mentioned, a sectional view through one of the end piece blanks showing the precious metal drawn around over the base metal and showing the smooth edges trimmed.

Fig. 1X represents a view similar to Fig. VH1 but with two of the end piece members assembled in proper relation to bring out that the entire outer or exposed surface of the end piece is covered with the precious metal shell 7 entirely protecting the base metal core portion or inner face 8, except at the temple slot 9 formed by the two offset portions 3, while as the temple will later fill up this slot there is no visible base metal at this point in the final frame.

I wouldcall particular attention to the fact that as referred to this process is particularly adapted for use in connection with gold-filled stock, as is illustrated in the drawings, for the reason that in stock of this sort the precious metal shell is secured on one side only of theoriginal plate when the operation of stamping or pressing the sheet with the precious metal shell toward the dies will drawn around the edges of the blank to be employed and extend up to the inner face of the end piece so that when the bur is removed the entlre outer or exposed portion of the article will be covered with the precious metal, as is clearly illustrated in Fig. IX, the base metal portions being secured together and in this way an extremely desirable article is produced entirely protected as respects the outer surface.

I claim- 1. The process of forming an end piece from combination materials, consisting in stamping the form in a shaping die which will draw the shell of one material up around the opposite material and subsequently severing the parts on a plane intersecting the drawn up outer material on both sides to provide an article, exposing one form of metal on one face and the opposite form on the other face and sides, substantially as illustrated.

2. The process of forming end pieces which consists in stamping the form in the blank, punching the form from the blank and then transversely cutting the form to trim the burs from the form caused by the punching of the form from the blank.

3. The process of forming a spectacle end piece consisting in securing together two sheets of different characters of material, one being of precious metal, stamping the combined sheet to produce a depressed form having the precious metal drawn up around the edges thereof to a point above the depressed face of the non-precious metal, and completing the article by transversely severing the parts through the drawn up precious metal to produce an end piece having precious metal covered sides, substantially as illustrated.

4. The process of forming filled end piece members or the like, consisting in stamping a sheet of filled material to produce a protuberance of desired shape, having the pre cious metal drawn therearound, punching the drawn up article from the sheet, laterally supporting the punched out article, and transversely cutting the article in the direc tionof the transverse support to remove the bur produced by the punching out action.

In testimony whereof Ihave afliXed my signature, in presence of two witnesses.
